According to the introduction of nine-day microsatellites, on December 7, 2018, nine-day microsatellites launched ladybug series satellites to verify the development capability of 100-kilogram satellites, and will carry out system-level verification of the Internet of Things in wildlife protection, field emergency rescue and other fields. Among them, ladybug-1 satellite carries space self-timer, star scintillation and space VR loads developed jointly with Xiguang Institute of Chinese Academy of Sciences and Zhongke Tianta. At present, the satellite has completed platform test and load test, and its function is normal. On December 25, 2018, Ladybug 1 first tested the starlight scintillation load. The star sensor developed by the Nine-day Microstar Partner Star Galaxy captured Merry Chrismas, the Moss code dot line that flickered on the ground on that day, and measured the actual brightness of the flickering stars as -0.5.
In addition, the nine-day microsatellite also announced that some satellites were in orbit, such as Huamixing, Tianmao International, RE:X, Elvis Presley Radio and Likeda Education Satellite, which operated steadily, had sufficient power and normal platform and load functions. The above satellites were passive temperature control designed by Nanjing University of Technology.
At present, the ladybug series cubic satellites have completed two technical schemes on-orbit verification: one is to achieve 65W maximum power on 6U cubic satellites, and the other is to adopt a rigid-flexible integrated battery array design scheme on 6U platform. Subsequently, the application scenario verification of the Internet of Things will be carried out based on digital phased array technology.
Finally, in 2019, the Nine-day Microstar Program will cooperate with China Science and Technology Tianta, Eight Aerospace Academies and Great Wall Corporation in the One Arrow, Four Stars project, with a budget of 200-300 million yuan. By 2022, the deployment of the constellation of the Internet of Things will be completed. It is estimated that a cumulative investment of 2 billion yuan will be required. (Qu Shun)
